mobile problems on ios - bold AND italics, and "jump to chat"

neither the features of simultaneous bold and italics like this nor the "jump to chat" button in search work on mobile on ios. Jump to chat simply takes you back to the bottom of the channel/dm rather than to the message, and bold or italics is just whichever is less nested. This has been a problem for years through multiple updates and there are posts months old about it and I would really like to see them both fixed please.
